Definitions

  • the present invention relates to a device for compensating for tolerances between a first component and a second component, comprising a base element which defines a longitudinal central axis, a compensation element which is in threaded engagement with the base element and a holding element which is fixedly connected to the base element for holding the device on the base element first component, wherein the holding element comprises a base body and wherein a support wall is formed on the base body, which has an upper edge facing away from the second component when the device is held on the first component.
  • Such a device is known in principle and is used in the automotive field, for example when installing a rail on the roof of a vehicle.
  • the device specifically serves to compensate for tolerances in the distance between a roof panel of the motor vehicle (first component) and an underlying support structure (second component) in the direction of the longitudinal central axis.
  • the device is clipped into a recess provided in the roof panel by means of its holding element and the compensating element is screwed out of the base element until it is supported downward on the support structure underneath and the clips of the holding element under the roof panel are supported upward on the roof panel.
  • a section of the base element protrudes upward beyond the roof sheet and forms a contact surface for the rail to be assembled.
  • the clips of the holding element are comparatively soft.
  • this is problematic in that the clips can be deformed correspondingly easily if the compensating element already engaged with the support structure is further rotated out of the base element, which can happen at increased torques, which can occur in particular when the compensation element is unscrewed using a tool provided specifically for this purpose.
  • Such an undesirable deformation of the clips leads to the base element projecting undefined far upwards above the roof panel, which in turn means that the rail, which is usually fixed to the roof by means of several devices, has an uneven gap to the roof panel over its length, which not only the external appearance, but also the function of a seal arranged between the railing and the roof panel is impaired.
  • the document EP 2 003 346 A2 shows a fastening device with tolerance compensation.
  • An object of the invention is to provide a device of the type mentioned at the outset, which can be assembled with little effort and, in the assembled state, ensures a defined protrusion of the base element beyond the first component on a side facing away from the second component.
  • a support wall is formed on the base body which, when the device is held on the first component, has an upper edge facing away from the second component and which comprises a deflection section which counteracts a restoring force can be deflected along a bending line that is not perpendicular to the longitudinal center axis.
  • the invention is based on the general idea of deriving a force exerted in the assembled state of the device by supporting the compensating element on the second component on the base element and the holding element via a support wall formed on the base element, which forms a deflection section which can be deflected along a bending line that is not perpendicular to the longitudinal center axis and runs diagonally through the supporting wall. Because of the course of the bending line that is not perpendicular to the longitudinal central axis, the deflection section can be compared with Deflect little force in a direction required for the assembly of the device in the recess of the first component transversely to the longitudinal central axis and clip it into the first component.
  • the support wall has a higher stability when viewed in the direction of the longitudinal central axis and can therefore transmit higher forces in this direction without undesirably deforming.
  • the basic element of the device held on the first component and supported on the second component always protrudes beyond the first component by a defined amount on the side facing away from the second component.
  • the base element, the compensating element and the holding element can be made of a plastic, such as polyoxymethylene. However, it is also conceivable to manufacture the base element and the compensation element in particular from a metal material.
  • the base element and the holding element are preferably positively and / or non-positively connected to one another, for example pressed.
  • the supporting wall advantageously has a constant wall thickness.
  • the supporting wall it is also conceivable for the supporting wall to have different wall thicknesses, it being possible for the wall thickness to be narrower, in particular to the outside, for easier insertion of the device into the recess in the first component.
  • the deflection section has a different, in particular thinner, wall thickness than a section of the support wall that is not deflected.
  • the supporting wall preferably has an outer edge with an extension component parallel to the longitudinal central axis, the outer edge and the bending line being spaced apart from one another. The distance between the outer edge and the bending line defines a lever length.
  • the distance between the outer edge and the bending line advantageously increases in the direction of the upper edge. Since less force has to be applied with a longer lever length in order to deflect a lever, the force to be deflected for deflecting the deflecting section decreases in the direction of the upper edge, which results in a degressive force curve when the device is clipped into the first component.
  • the outer edge does not necessarily have to run parallel to the longitudinal central axis.
  • a distance between the outer edge and the longitudinal central axis can increase in the direction of the upper edge.
  • the bending line runs diagonally through the supporting wall in the direction of the outer edge, starting from an area in which the upper edge emerges from the base body.
  • a pair of support walls spaced apart from one another in the circumferential direction of the base body is advantageously provided.
  • a pair of supporting walls is provided on opposite sides of the base body. It proves to be advantageous if two pairs of supporting walls are arranged diametrically to one another on the base body, it also being possible to arrange two pairs of supporting walls not diametrically to one another. In principle, it is also conceivable that more than two pairs of support walls on the base body are trained. It is also conceivable to design only one support wall of a pair of support walls with a deflection section.
  • Clipping the device into the recess of the first component is additionally facilitated by the fact that the distance between the support walls of a pair of support walls increases in the direction of the upper edge, that is to say the support walls diverge upwards.
  • the device is also securely clipped to the first component if the distance between the support walls of a pair of support walls increases outwards from the base body.
  • the support walls of a pair of support walls spread outwards from the base body, and their deflection sections can be pressed together for inserting the device into the recess.
  • this ensures that the upper edges of the support walls forming the support surfaces come to rest at least partially under an area of the first component delimiting the cutout and can be supported effectively on the latter.
  • the support walls of a pair of support walls are preferably curved away from one another.
  • the course of the curvature ensures that the outer edges of the support walls only run onto the edge of the first component that delimits the cutout, as a result of which the deflection sections are deflected with the maximum lever arm when the device is inserted into the cutout, which minimizes the force to be applied for clipping in the device .
  • the device clipped into the recess can be rotated about the longitudinal central axis when the compensating element comes out of the base element is turned out.
  • the support walls can be aligned at different angles ⁇ , ⁇ to a plane which contains the longitudinal central axis and extends centrally between origins of the support walls on the base body.
  • the upstream angle ⁇ viewed in the direction of rotation, is advantageously smaller by the angle ⁇ than the angle ⁇ , so that the support walls are at least approximately symmetrically aligned with the recess after the device has been rotated through the angle ⁇ .
  • a region of a retaining wall is defined as the origin at which this emerges from the base body.
  • a set of first rotation-limiting surfaces is provided on the holding element, in particular by the rotational movement to the angle mentioned ⁇ limit.
  • a set of second rotation-limiting surfaces can be provided on the holding element in order to limit rotation of the device accommodated in the recess of the first component about the longitudinal central axis in a direction that is opposite to a rotary movement caused by unscrewing the compensating element from the base element .
  • the holding element can form a projection on an end of the base body facing away from the second component, which projection, together with the upper edge of the support wall, serves to secure the device on the first component.
  • the projection and the upper edge are spaced apart from one another in such a way that they can accommodate an edge region of the first component defining the recess between them.
  • the distance between Cantilever and upper edge at least approximately adapted to the thickness of the edge area of the first component.
  • the set of first rotation limitation surfaces and / or the set of second rotation limitation surfaces are advantageously formed between the projection and the upper edge.
  • the base body defines in the circumferential direction a frame with a pair of opposing frame walls, each frame wall being assigned a support wall spaced apart from it. Each support wall can be aligned essentially parallel to its frame wall.
  • Each support wall preferably comprises two deflecting sections pointing away from one another, which are defined by a web which extends in the direction of the longitudinal central axis and connects the support wall and the frame wall and by a console facing the second component and connecting the support wall and the frame wall.
  • each deflection section preferably runs diagonally from an end of the web facing away from the second component through the supporting wall in the direction of a region of an outer edge of the supporting wall facing the second component.
  • an extension extends outward from each deflection section.
  • the extensions of a support wall preferably merge into a projection which connects the extensions and which can protrude beyond an edge region of the first component which delimits the recess.
  • a counter bearing is formed on each deflection section, which counter support forms a support surface spaced apart in the direction of the longitudinal central axis.

Additionally or alternatively, a set of second positioning surfaces can be provided, which are formed on extensions of frame walls facing the support walls, which extend at least approximately perpendicular to the support walls.
  • attack features in particular for a tool, such as pliers, can be provided on the extensions, by means of which the deflection sections can be deflected against their restoring force.
  • the cantilever can provide protection for the first component against damage from the tool.
  • FIG. 1 A device 10 according to the invention is shown according to a first embodiment.
  • the device 10 comprises a basic element 12 which defines a longitudinal central axis A, a compensating element 14 and a holding element 16 and serves to compensate for tolerances between a first component 18, for example a roof panel of a motor vehicle, and a second component 20, for example one under the roof panel horizontal support structure (see Fig. 4 ).
  • the base element 12 and the compensation element 14 are in threaded engagement with one another, so that by rotating the compensation element 14 about the longitudinal central axis A, the compensation element 14 can be turned out of the base element 12 in the direction of the second component 20 in order to be supported there by means of a stop disk 21 ( Fig. 4 ).
  • the holding element 16 comprises a base body 22 pressed onto and / or glued to the base element 12 with two diametrically arranged pairs of support walls 24 which form an origin 26 where they emerge from the base body 22.
  • the number of support walls 24 can differ from four.
  • the support walls 24 can also be formed elsewhere on the base body 22.
  • the support walls 24 each have an abutment disk 21 or, when the device 10 is assembled, an upper edge 28 facing away from the second component 20, which defines a support surface 29 here.
  • Each of the support walls 24 also has an outer edge 30 and comprises a deflection section 32, which can be deflected against a restoring force and is separated from a rigid section 34 by a bending line B.
  • the bending line B originates from an area in which the support surface 29 of a support wall 24 emerges from the base body 22, runs diagonally through the support wall 24 in the direction of its outer edge 30, wherein in Fig. 3 the bending line B is only shown as an example on a support wall 24. In other words, the distance between the bending line B and the outer edge 30 increases in the direction of the upper edge 28.
  • each support wall 24 The distance between the longitudinal central axis A and the outer edge 30 of each support wall 24 increases in the direction of the upper edge 28, the support walls 24 are raised to a certain extent.
  • the distance between the support walls 24 of a pair of support walls 24 decreases in the direction of the stop disc 21. In other words, the support walls 24 of a pair diverge upwards. In addition, the support walls 24 of each pair of support walls 24 are curved away from each other ( 5 and 6 )
  • Fig. 3 shows the device 10 as it is partially inserted into a recess 36 of the first component 18. Due to the decreasing distance between the support walls 24 of a pair of support walls 24 in the direction of the stop disk 21, each pair of support walls 24 has an undersize in relation to the recess 36 in an area facing the stop disk 21 and an oversize in comparison to the area in a region facing away from the stop disk 21 Recess 36, which effect is further enhanced by the curvature of the support walls 24.
  • the device 10 can be inserted into the recess 36 without any effort to a depth in which the outer edges 30 of the support walls 24 come into contact with an edge of the first component 18 which delimits the recess 36. From this point onwards, a greater expenditure of force is required for the further insertion of the device 10, since the further insertion of the device 10 can only take place by compressing the support walls 24.
  • the deflection sections 32 of the support walls 24 become through the edge delimiting the recess 36 as the device 10 penetrates into the recess 36 of the first component 18 is deflected along the bending line B against its restoring force.
  • the deflection sections 32 After passing through the recess 36, the deflection sections 32 return to their original rest positions as a result of the restoring force and engage behind the edge region of the first component 18 which delimits the recess 36, ie the device 10 is now clipped into the first component 18.
  • Fig. 4 shows the device 10 after clipping into the first component 18 and in a final assembly state, in which both the support walls 24 are supported on the underside of the first component 18 and the compensating element 14 is turned out of the base element 12 and is in contact with the stop disk 21 is supported against the second component 20.
  • radially outwardly projecting projections 38 are provided on the base body 22, which are axially spaced from the support surface 29 of the support walls 24 and together with the support walls 24 form a receptacle for the first component 18.
  • the projections 38 are formed on an end of the holding element 16 facing away from the second component 20, specifically in the form of four projecting shoulders which are arranged in an evenly distributed manner around the base body 22 in relation to the support walls 24. It goes without saying that the projections 38 can in principle also be aligned with the support walls 24, i.e. can be arranged directly above this. In addition, the number of overhangs 38 may differ from four.
  • a radially projecting collar 40 is formed in an end region of the base element 12 facing the second component 20 (circumferentially) Fig. 1 ).
  • the collar 40 has, on a side facing the second component 20, circumferentially distributed depressions 42 which extend radially inward from an outside of the collar 40, so that a section of the collar 40 facing away from the second component 20 projects from the depressions 42.
  • the recesses 42 serve to receive locking projections 44 of the holding element 16, which the facing the second component 20 are each formed between two supporting walls 24. Through the locking projections 44 engaging in the recesses 42, the holding element 16 is additionally secured against axial displacement relative to the base element 12.
  • the compensating element 14 can be rotated out of the base element 12 by rotating about the longitudinal central axis A, which can cause the device 10 to rotate in the recess 36 of the first component 18, in particular if a hole pattern of the recess 36 is produced by a standard hole pattern due to production deviates.
  • the rotation of the device 10 is greater the larger the actual recess 36a, 36b is compared to a recess 36 with a standard dimension ( 5 and 6 ).
  • a set of first rotation limiting surfaces 46 is formed on the holding element 16.
  • a set of second rotation limiting surfaces 48 is provided which limit rotation of the device 10 in the opposite direction.
  • Each set of rotation restriction surfaces 46, 48 includes a pair of rotation restriction surfaces 46a, 48a that are formed in close proximity to the support walls 24 and a pair of rotation restriction surfaces 46b, 48b that are formed away from the support walls 24.
  • the pairs of rotation limitation surfaces 46b, 48b, which are formed remotely from the support walls 24, have different dimensions when viewed from the base body 22, the pair of rotation limitation surfaces 46b, which is assigned to the set of first rotation limitation surfaces 46, being larger towards the outside is dimensioned as the pair of rotation limitation surfaces 48b which is assigned to the set of second rotation limitation surfaces 48.
  • Both sets of rotation limiting surfaces 46, 48 are formed between the support walls 24 and the projection 38, viewed in the direction of the longitudinal central axis A. Since the first component 18 is received between the support walls 24 and the projection 38 in the clipped-in state of the device 10, the rotation-limiting surfaces 46, 48 can abut against the edge of the first component 18 delimiting the recess 36 when the device 10 is rotated.
  • FIG. 5 and 6 show the holding element 16 received in the recess 36 from below, ie from the perspective of the second component 20 with a view towards the first component 18 shown schematically Fig. 5 the actual recess 36a (solid line) is smaller than the recess 36 with standard dimensions (broken line), whereas in Fig. 6 the actual recess 36b (solid line) is larger than the recess 36 with standard dimensions (broken line).
  • both sets of rotation-limiting surfaces 46, 48 contribute to a correct alignment of the support walls 24, so that when the device 10 is assembled there is as large an overlap as possible between the support walls 24 and the first component 18 .
  • the holding element 16 rotates due to the perspective in FIG 5 and 6 counterclockwise from below, and the set of first rotation limiting surfaces 46 abuts the first component 18, thereby limiting the rotational movement of the holding element 16.

This reduces the angle ⁇ between the one support wall 24 and the plane F. the difference angle ⁇ , whereas the angle ⁇ between plane F and the other support wall 24 increases by the difference angle ⁇ , so that as a result both support walls 24 have an approximately equal overlap with the inner surface of the first component 18.

  • another type of fastening of the base element 12 to the holding element 16 is also conceivable, for example by gluing.
  • the frame walls 52 of one of the pairs of opposite frame walls 52 are each assigned a substantially parallel spaced support wall 24, which in an area adjacent to an upper edge 28 of the support wall 24 through a web 58 and in an area facing the second component 20 a bracket 60 is connected to the respective frame wall 52.
  • the web 58 runs parallel to the longitudinal central axis A and is attached centrally to the frame wall 52 and the support wall 24.
  • the console 60 extends over the entire width of the support wall 24.
  • Each support wall 24 forms two deflection sections 32 facing away from one another and pointing away from the web 58, each of which is separated from a rigid section 34 by a bending line B. Starting from the web 58, each bending line B runs diagonally through the support wall 24 in the direction of a region of an outer edge 30 of the support wall 24 facing the second component 20.
  • each bracket 60 forms stiffening sections 62 starting from the web 58 and extending diagonally outwards in the direction of the second component 20, the slopes of the stiffening sections 62 being steeper than the slopes of the diagonally running bending lines B.
  • An extension 64 extends from each deflection section 32 of a support wall 24 in the region of the upper edge 28 of the support wall 24 away from the base element 12.
  • the extensions 64 of a support wall 24 merge into a projection 38 connecting the extensions 64.
  • two counter bearings 66 projecting outward and forming support surfaces 29 in the direction of the upper edge 28 are formed on each support wall 24, in each case in the region of the outer edges 30 of the deflection sections 32.
  • the counter bearings 66 are in the direction of the second component 20 Projection 38 axially spaced and together with the projection 38 form a receptacle for the first component 18.
  • each support wall 24 is curved outwards from the web 58 in the direction of its two outer edges 30.
  • each support wall 24 in the non-clipped-on state of the device 10 on the first component 18 in the region of its outer edges 30 has a certain excess compared to a recess 36 of the first component 18, not shown here.
  • each support wall 24 presses resiliently at least in sections between the extensions 64 and the counter-bearings 66 against an edge of the first component 18 delimiting the recess 36 in order to define a set of first positioning surfaces 68a there contribute to the positioning of the device 10 in the recess 36.
  • those frame walls 52 which run at least approximately perpendicular to the support walls 24 form a set of second resilient positioning surfaces 68b in the region of their corners facing the support walls 24 and away from the second component 20 in order to position the device 10 in the recess 36.
  • the set of second positioning surfaces 68b viewed in the direction of the longitudinal central axis A, is at a height which lies between the projection 38 and the counter bearing 66, so that the set of second ones Positioning surfaces 68b in the assembled state of the device 10 press against the edge of the first component 18 delimiting the recess 36.
  • both the set of first positioning surfaces 68a and the set of second positioning surfaces 68b By pressing both the set of first positioning surfaces 68a and the set of second positioning surfaces 68b against the edge of the first component 18 which delimits the cutout 36, they contribute to the radial positioning of the device 10 in the cutout 36 and also ensure one in the case of cutouts 36 which are subject to tolerances sufficient overlap between the support surfaces 29 and the first component 18.
  • the counter bearings 66 come into contact with the edge of the first component 18 delimiting the recess 36 from a certain depth. Applying a force to the device 10 along the longitudinal central axis A in the direction of the second component 20, the device 10 is pressed further into the recess 36, as a result of which the deflection sections 32 are deflected via the counterbearing 66 against the restoring force of the deflection sections 32.
  • the force to be deflected to deflect the deflecting sections 32 decreases degressively with increasing depth of penetration of the device 10 into the recess 36, since because of the diagonal bending line B, a lever length with which the deflecting sections 32 are deflected increases in the direction of the upper edge 28.
  • the deflection sections 32 and thus also the counter bearings 66 formed thereon return due to the restoring force of the deflection sections 32 in the direction of their original rest positions, so that the support walls 24 press at least in sections against the edge region of the first component 18 delimiting the recess 36 and the support surfaces 29 of the counterbearing 66 engage behind the edge region of the first component 18 delimiting the recess 36.
  • an attack feature 70 is formed on the extensions 64, which is used with the aid of a tool (not shown), for example pliers, to deflect the deflection sections 32 against their restoring force, so that the device 10 extends the recess 36 can be pulled out again.
  • a tool for example pliers
  • the projection 38 is widened outwards in order to serve as protection.
